[0035] The present application will be described in detail below with reference to the various embodiments shown in the accompanying drawings.

[0036] In the various figures of the present application, for the sake of convenience, some dimensions of structures or parts are exaggerated relative to other structures or parts, and therefore, are only used to illustrate the basic structure of the subject matter of the present application.

[0037] It should be understood that although the terms first, second, etc. may be used in this document to describe various elements or structures, these described objects should not be limited by these terms. These terms are only used to distinguish these described objects from each other.

[0038] Referring to Figures 1 to 3, a refrigeration device 100 provided in one embodiment of the present application includes a housing 1 and a door. The housing 1 defines a refrigeration space for storing and refrigerating items. The door is assembled to the housing 1 and can rotate relative to the housing 1 to open or close the refrigeration space. Refrigeration device 100 can specifically be a refrigerator, freezer, wine cabinet, etc.

[0039] For ease of description, in this embodiment, the description is carried out by taking the refrigeration device 100 placed on the ground or on a base as an example. When the door is closed, the user faces the door as a reference, and the direction from the door toward the box body 1 is defined as the direction from front to back. The direction of the box body 1 relative to the ground or the base is up, and the opposite direction is down. When the user faces the door from the front, the left and right sides of the user are defined as left and right, respectively.

[0040] The housing 1 includes a rear wall 11 and a pair of side walls connected to the rear wall 11, one of which is provided with a first air inlet 14. Specifically, in this embodiment, the pair of side walls includes a left side wall 12 and a right side wall 13, which are arranged opposite each other. The left side wall 12 is connected to the left end of the rear wall 11, and the right side wall 13 is connected to the right end of the rear wall 11. The first air inlet 14 is provided on the right side wall 13. In other embodiments, the first air inlet 14 may also be provided on the left side wall 12.

[0041] The housing 1 defines a press chamber 2 at its rear lower portion, which defines a built-in space. The press chamber 2 includes a rear cover 21 located behind the built-in space. A second air inlet 211 is provided at the end of the rear cover 21, which is closer to the first air inlet 14. An air outlet is provided at the end of the press chamber 2, which is farther from the first air inlet 14. The first air inlet 14, the second air inlet 211, and the air outlet are all connected to the built-in space. In other words, air enters the press chamber 2 through the first air inlet 14 and the second air inlet 211, and air exits through the air outlet.

[0042] In this way, the compressor chamber 2 can simultaneously take in air through the first air inlet 14 located on the side wall and the second air inlet 211 located on the rear cover 21 of the compressor chamber 2, thereby increasing the flow rate of cold air entering the compressor chamber 2, and the rear cover 21 of the compressor chamber 2 can play a role in blocking the wind, thereby limiting the air flow path in the compressor chamber 2, making the cold air flow in a directional manner, and improving the heat exchange efficiency. The rear cover 21 of the compressor chamber 2 can also play a protective role such as dust and rodent prevention.

[0043] Furthermore, the refrigeration device 100 further includes a wind shield 6 , which separates the second air inlet 211 from the air outlet, thereby preventing the mixing of cold and hot air, which would lead to a decrease in heat dissipation efficiency and an increase in energy consumption.

[0044] Referring to Figure 2 , in this embodiment, the windshield 6 includes a first section 61, a second section 62, and a third section 63, which are sequentially connected. The first section 61 is located above the second air inlet 211, the third section 63 is located below the air outlet, and the second section 62 connects the first section 61 and the third section 63. The segmented windshield 6 structure allows for flexible placement based on the location of the air inlet and outlet, achieving excellent windshield performance.

[0045] Preferably, the left end of the wind shield 6 is connected to the left side wall 12, and the right end of the wind shield 6 is connected to the right side wall 13, thereby improving the wind shielding effect.

[0046] Preferably, the first section 61 and the third section 63 both extend transversely to facilitate processing and save materials.

[0047] Furthermore, the air outlet includes a first air outlet located above the built-in space, and the third section 63 is located below the first air outlet, thereby separating the first air outlet and the second air inlet 211.

[0048] Furthermore, the air outlet also includes a second air outlet 212, which is located at an end of the rear cover 21 away from the first air inlet 14 and below the first air outlet. The third section 63 is located below the second air outlet 212. The arrangement of the first and second air outlets 212 increases the air outlet area, further improving heat dissipation efficiency. The third section 63 is located below the second air outlet 212, thereby isolating the first air outlet from both air outlets to prevent air mixing.

[0049] 4 and 5 , the refrigeration device 100 further includes an air guide 3, which is disposed at a side end of the rear wall 11 and above the built-in space. The first air outlet is located in the air guide 3. The coordinated structure of the air guide 3 and the first air outlet allows the hot air discharged from the first air outlet to be directed and discharged upward as quickly as possible, thereby improving heat dissipation efficiency.

[0050] Specifically, the air guide member 3 includes a main body 31 and a first recess 32 that is recessed forward from the main body 31. The first recess 32 defines a first air guide groove, which is connected to the press chamber 2. The first recess 32 is located between the main body 31 and the side wall connected to the side end where the air guide member 3 is located.

[0051] In this way, the first air guide groove can be deepened near the side wall with the help of the structure of the refrigeration device 100 itself. On the one hand, the thickness of the foam layer near the side wall can be utilized to deepen the first air guide groove here, which not only increases the air outlet area, but also does not affect the thermal insulation performance of the foam layer, thereby avoiding an increase in the energy consumption of the refrigeration device 100. On the other hand, the main body 31 is close to the refrigeration space. Such a setting can avoid thinning the thickness of the foam layer in the refrigeration space, thereby avoiding an increase in the energy consumption of the refrigeration device 100.

[0052] In this embodiment, the air guide 3 is provided at the left end of the rear wall 11, and the left end of the rear wall 11 is connected to the left side wall 12, that is, the first recess 32 is located between the main body 31 and the left side wall 12. In other embodiments, the air guide 3 may be provided at the right end of the rear wall 11, and the right end of the rear wall 11 is connected to the right side wall 13, that is, the first recess 32 is located between the main body 31 and the right side wall 13.

[0053] Preferably, the first recess 32 is located between the refrigeration space and the side wall connected to the side end where the air guide 3 is located. In this way, the main body 31 is correspondingly arranged at the rear of the refrigeration space. The structural design of the air guide 3 can not only maintain the thermal insulation effect of the foam layer of the refrigeration device 100 itself, but also maximize the air outlet area of ​​the compressor chamber 22 and improve heat dissipation efficiency.

[0054] In this embodiment, since the air guide 3 is provided at the left end of the rear wall 11, the left end of the rear wall 11 is connected to the left side wall 12, that is, the first recess 32 is located between the refrigeration space and the left side wall 12. In other embodiments, if the air guide 3 is provided at the right end of the rear wall 11, and the right end of the rear wall 11 is connected to the right side wall 13, the first recess 32 is located between the refrigeration space and the right side wall 13.

[0055] Referring to Figures 6 to 8 , the air guide 3 further includes a second recess 33, which is located below the main body 31 and recessed forward from the main body 31. The second recess 33 is connected to the first recess 32, and the first air outlet of the compressor compartment 2 is connected to the second recess 33. Thus, the second recess 33 defines a second air guide groove, which connects the first air outlet and the first air guide groove. This allows hot air in the compressor compartment 2 to be discharged through the air guide 3, thereby improving the heat dissipation efficiency of the compressor compartment 2.

[0056] The specific location of the air guide 3 is related to the location of the first air outlet of the press chamber 2. In this embodiment, the first air outlet of the press chamber 2 is correspondingly located at the upper left portion of the press chamber 2, and the air guide 3 is located above the press chamber 2. In other embodiments, the first air outlet of the press chamber 2 may also be located at the upper right portion of the press chamber 2, and the air guide 3 is correspondingly located at the right end of the rear wall 11 and above the press chamber 2, so as to shorten the air path and improve heat dissipation efficiency.

[0057] Furthermore, a centrifugal fan 4 is provided in the compressor chamber 2, and an air outlet 41 of the centrifugal fan 4 is located in the second recess 33. In this way, the heat dissipation efficiency of the compressor chamber 2 can be further improved by the high efficiency of the centrifugal fan 4.

[0058] Furthermore, the centrifugal fan 4 includes a volute 42 and a cover plate 43 arranged in front and back relative to each other, and the volute 42 and the cover plate 43 enclose an exhaust port 41 of the centrifugal fan 4. In this embodiment, the exhaust port 41 of the centrifugal fan 4 is located in the first air outlet of the compressor chamber 2.

[0059] In this embodiment, the volute 42 and the cover plate 43 are fixedly assembled by screws 5. Both the volute 42 and the cover plate 43 are provided with screw holes. The screws 5 pass through the screw holes of the volute 42 and the cover plate 43 to achieve the assembly of the two. Multiple groups of screws 5 and screw holes are provided in a one-to-one correspondence, preferably three groups. The three groups of screws 5 and screw holes are evenly spaced along the circumference of the volute 42. In other embodiments, the volute 42 and the cover plate 43 can also be assembled using a snap-fit ​​structure or other structures.

[0060] The centrifugal fan 4 also includes an impeller 44. The volute 42 and cover plate 43 together enclose a volute air duct, within which the impeller 44 is disposed. In this embodiment, the exhaust port 41 of the centrifugal fan 4 is located at the upper end of the volute air duct, thereby facilitating the discharge of hot air from the compressor compartment 2 through the rear of the refrigeration unit 100 and upward. The air intake 45 of the centrifugal fan 4 is located in the volute 42, opposite the impeller 44.

[0061] Specifically, in this embodiment, the impeller 44 is assembled with the cover plate 43 by screws 5. Both the impeller 44 and the cover plate 43 are provided with screw holes. The screws 5 pass through the screw holes of the impeller 44 and the cover plate 43 to achieve the assembly of the two. There are multiple groups of screws 5 and screw holes corresponding to each other, preferably three groups. The three groups of screws 5 and screw holes are evenly spaced along the circumference of the impeller 44. The screw holes on the cover plate 43 for fixing the impeller 44 are staggered with the screw holes for fixing the volute 42 to avoid affecting the assembly. In other embodiments, the impeller 44 and the cover plate 43 can also be assembled by a snap-fit ​​structure or other structures.

[0062] During assembly, the impeller 44 and the cover plate 43 are first assembled, and then the volute 42 is fastened to the outside of the impeller 44 . The volute 42 and the cover plate 43 are then fixed together by screws 5 , thereby completing the assembly of the centrifugal fan 4 .

[0063] Furthermore, the cover plate 43 is located behind the volute 42, and the volute 42 is located in front of the cover plate 43. The rear surface of the cover plate 43 is coplanar with the outer wall surface of the rear wall 11. In this way, the centrifugal fan 4 can be placed in the upper rear part of the compressor chamber 2, which not only frees up the storage space at the bottom of the compressor chamber 2 to facilitate the reasonable arrangement of the various components of the refrigeration system, but also extends the air path in the compressor chamber 2 to take away more heat in the compressor chamber 2 and improve the heat dissipation efficiency.

[0064] The air guide 3 is located above the built-in space. The air guide 3 also includes a sealing portion extending forward from the lower end of the second recess 33. The sealing portion is located in the press chamber 2, thereby improving the sealing of the box body 1 and preventing foaming and overflow.

[0065] Furthermore, the rear wall 11 includes a back plate 111 and an opening provided in the back plate 111, the opening facing downward and located above the press chamber 2, and the air guide 3 is located at the opening and is mated with the back plate 111. In other words, by providing an opening in the back plate 111 for assembling the air guide 3, the manufacturing process can be simplified and costs can be saved.

[0066] Preferably, the back panel 111 is located above the press chamber 2. In this embodiment, the position of the opening corresponds to the first air outlet of the press chamber 2. The opening is arranged at the lower left part of the back panel 111 and faces downward. In other embodiments, if the first air outlet of the press chamber 2 is arranged at the upper right part of the press chamber 2, the opening is correspondingly arranged at the lower right part of the back panel 111.

[0067] Specifically, the air guide 3 is assembled to the back plate 111 using screws 5. Preferably, the air guide 3 is assembled to the back plate 111 using three sets of screws 5 and screw holes, with one set of screws 5 and screw holes located above the opening, and the other two sets of screws 5 and screw holes located on the left and right sides of the opening, respectively. This improves the assembly strength of the air guide 3 and the back plate 111. Of course, the number of screws 5 and screw holes is not limited to this.

[0068] 9 to 12 , further, a flange 1111 is provided on the edge of the back panel 111 toward the opening, and a card slot 34 is provided on the edge of the air guide 3, and the flange 1111 is snapped into the card slot 34. Through the matching structure of the flange 1111 and the card slot 34, not only can the assembly firmness of the air guide 3 and the back panel 111 be strengthened, but also foaming overflow can be prevented.

[0069] Preferably, the flange 1111 is formed around the opening. Specifically, since the opening faces downward, that is, the flange 1111 is formed around the left edge, upper edge and right edge of the opening, and the slot 34 is arranged to correspond to the flange 1111 to improve the sealing of the back panel 111 and the air guide 3 to prevent foaming and overflow.

[0070] Preferably, a sealing sponge is further provided at the card slot 34 to further improve the sealing performance.

[0071] Furthermore, the main body 31 is located in front of the outer surface of the rear wall 11, or the rear surface of the main body 31 is coplanar with the outer surface of the rear wall 11. This not only facilitates air flow, but also prevents the main body 31 from protruding from the rear wall 11 and increasing the occupied space of the refrigeration device 100.

[0072] After the air guide 3 is assembled on the back plate 111, the back plate 111 is assembled with the bottom steel. Preferably, the air guide 3 and the bottom steel can be assembled by screws 5 to improve the assembly strength of the air guide 3 and the box body 1; then the pre-installed centrifugal fan 4 is assembled with the box body 1.

[0073] Specifically, the pre-assembled centrifugal fan 4 can be assembled to the housing 1 using screws 5. In this embodiment, the centrifugal fan 4 and the housing 1 are assembled using three sets of screws 5 and screw holes, two of which are located at the upper end of the centrifugal fan 4 and on the left and right sides of the exhaust port 41 of the centrifugal fan 4, and another set of screws 5 and screw holes assemble the centrifugal fan 4 to its adjacent side walls. In this embodiment, since the air guide 3 is located at the left end of the rear wall 11, the centrifugal fan 4 is assembled to the left side wall 12 using screws 5 and screw holes. In other embodiments, if the air guide 3 is located at the right end of the rear wall 11, the centrifugal fan 4 is assembled to the right side wall 13 using screws 5 and screw holes.

[0074] In addition, a compressor is provided in the compressor chamber 2, and the first air inlet 14 and the second air inlet 211 are both provided close to the compressor.

[0075] In this embodiment, the compressor is located on the right side of the compressor compartment 2. Correspondingly, the first air inlet 14 is arranged on the left side wall 12 and is opposite to the compressor, and the second air inlet 211 is arranged on the rear cover 21 and is opposite to the compressor, thereby improving the heat dissipation efficiency of the compressor.

[0076] 13 and 14 , an embodiment of the present application further provides an embedded refrigeration device 1000, comprising a cabinet 200 and the aforementioned refrigeration device 100. The cabinet 200 defines a storage space, and the refrigeration device 100 is built into the storage space, so that the refrigeration device 100 can be embedded in the cabinet 200, making it look like an integral part of the kitchen or living room, thereby realizing an integrated kitchen appliance home decoration style.

[0077] Among them, the cabinet 200 includes a cabinet body 201, a cabinet door 202 and a base located at the bottom of the cabinet body 201. The cabinet body 201 defines the storage space, and the refrigeration device 100 can be placed on the base. The cabinet door 202 is assembled in the cabinet body 201 and can be rotated relative to the cabinet body 201 to open or close the storage space to operate the refrigeration device 100 built therein.

[0078] Furthermore, the cabinet 200 also includes a back panel 203 and a pair of side panels arranged opposite to each other on the left and right sides, the pair of side panels are a left side panel 204 and a right side panel 205, and the left and right ends of the back panel 203 are connected to the left side panel 204 and the right side panel 205 respectively.

[0079] A cabinet vent 206 is provided on the side panel corresponding to the first air inlet 14. The cabinet vent 206 communicates with the first air inlet 14, allowing cool air from the external environment to enter the first air inlet 14 through the cabinet vent 206 and then flow into the compressor compartment 2. In this embodiment, the cabinet vent 206 is provided on the left side panel 204 to shorten the air intake path. Preferably, the cabinet vent 206 is provided on the left side panel 204 corresponding to the first air inlet 14. In other embodiments, if the first air inlet 14 is provided on the right side wall 13, the cabinet vent 206 is provided on the right side panel 205.

[0080] An air supply port is provided at the base of the cabinet 200, and an air supply duct is defined at the base of the cabinet 200. The air supply duct is connected to the second air inlet 211 through the air supply port, so that the compressor compartment 2 can take in air from the bottom of the refrigeration device 100 and then through the second air inlet 211 at the rear thereof.

[0081] Preferably, when the refrigeration device 100 is built into the accommodating space of the cabinet 200, the rear end of the wind shield 6 abuts against the rear panel 203 of the cabinet 200, so that the air inlet and the air outlet can be completely isolated, and the air inlet channel and the air outlet channel can be limited with the help of the cabinet 200 to improve the heat dissipation efficiency.

[0082] Compared with the prior art, the refrigeration device 100 provided in the present application and the embedded refrigeration equipment 1000 having the same have the following beneficial effects: the compressor chamber 2 can simultaneously take in air through the first air inlet 14 located on the side wall and the second air inlet 211 located on the rear cover 21 of the compressor chamber 2, thereby increasing the flow rate of cold air entering the compressor chamber 2, and the rear cover 21 of the compressor chamber 2 can act as a windbreak, thereby limiting the air flow path in the compressor chamber 2, making the cold air flow in a directional manner, and improving the heat exchange efficiency. The rear cover 21 of the compressor chamber 2 can also play a protective role such as dust and rodent prevention.
